T0 all wh0m z'z5 ma y concem:

Be it known that I, EDWARD G. VON GUNTEN, a citizen of the Unitecl Stabes, anal a resident 0: Akron, county 0f Summit, Stute of Ohio, have invencecl eertain new *ancl useful Improvements in Stminer Devices, 01": which the following is a specificution.

This inventiori relates to improvements in strainer clevices designecl particularly f01 use in straining milk, although itmay be usecl in conjunction with other liquide as Will presently appear.

The primary purpose of thepinvention is t0 provide a practieal anal inexpensive form of milk strainer which is acl&ptecl for separating the sediment from alle milk as .it is strainecl and also for entrapping the sedi ment in such a manner that it is 110t stirred up by succeecling q uantities 0f milk t0 he strainecl. The milk is, therefore, not strainecl through aceumulated secliment and is free from such impurities as it might therehy acquire.

One 0f the objects of the invention is to provide a form of milk strainer in which very fine wire mesh may be usecl, much finer mesh than Wih other forms of stminers. This invention is in the nature of an improvement in certain details upon a prior in- Vention Se1ial N0. 580,090, filecl August 7, 1922, the specifie objeets of alle invention being t0 simplify the construcnion ancl improve upon eertain details shown therein.

Other objects ancl advantages Will be appa1ent from the description ancl disclosure herein contained, it being understoocl that the details are non-essential und may loe varied within the scope of the invention ancl ehe claims appearing hereinafter.

In the drawings:

Figure 1 is a side view of the improved milk strainer;

Figure 2 is a vertieal section 011 the li11e 22 of Fig. l;

Figure 3 is a cross-section 011 the line 88 of Figura 2;

Figure 4 is a sicle elevation 0f th e disks 01' separators;

Figure 5 is a plan thereof; and.

Figure 6 is a persp eetive view of the top plante.

The inventiorg emhodies a, body portion er funnel 1 of sheei; quetf@ l; F9lll9?l a s shown und closed at its lowermost port1011. Upon opposite sicles 01 the funnel engl. spacecl from the bottom thereof are operaings 2 of suit able size coverecl with a fine ganze 01 wire sereen 3.

designated as the filtering chamber, und the lower seetion' 7 as the sediment trap. The

funnel atthe filtering chamber.

The funnel is clivided int0 these three chambers by an upper partition 8 and a lower partition 9. Euch partition is a disk of metal adapted to'fit against the Walls 01 the funnel except at definitely lo.cated p0ints where it is removed to allow the milk t0 flow into the next lower chamber. These openings 01 spaces are formed in any suitable way, as shown the disks are turned down along cords 10. These openings are preferably locatecl on opposite sides Cf the These openings may be of any su1table form to provide an openings 2 are located in the Walls of the disks ancl in the normal operation of the device are placed so as t0 be in line with the openings 2.

The two disks are preferably connectecl so as to loe properly spaced apart and prevented from relative rotation by an operating bar o1 tie rod 11 which is extencled above the upper disk to form a handle 12. T0 position the disks vso that the openings 10 are in line with the openings 2, in which positlon the device operates at greatest eifici ency the sides 01E the upper disk 8 are provided with pairs 01 spacecl lugs 01' knobs 13 which are adapted, as shown in Figure 3, to engage lugs 14 in the sicleWalls of the funnel.

In the operation 0f the device, the farmer or dairyman pours the milk into the upper chamber 5 from where it flows through the
